Origin, Evolution, and Modern Aspects of Biomineralization in Plants and Animals
The Fifth International Biomineralization Symposium was held in May 1986 at The University of Texas at Arlington, Arlington, Texas. The chosen theme was the origin, evolution and modern aspects of biomineralization in plants and animals. Thus, the symposium was designed to bring together experts in ocean and atmospheric chemistry, geochemistry, paleontology, biology, medicine and related fields to share accumulated knowledge and to broaden research horizons. The contents of this volume reflect the diversified interests and views of contributors from these fields. Topics range from contrasting views of the origin of ocean chemistry, the cause or causes for the biomineralization among plants a...
Nautilus
1. 1 Nautilus and Allonautilus: Two Decades of Progress W. Bruce Saunders Department of Geology Bryn Mawr College Bryn Mawr PA 19010 wsaunder@brynmawr. edu Neil H. Landman Division of Paleontology American Museum of Natural History New York, New York 10024 landman@amnh. org When Nautilus: Biology and Paleobiology of a Living Fossil was published in 1987, it marked a milestone in cross-disciplinary collaboration. More than half of the contributing authors (36/65) were paleontologists, many of whom were collaborating with neontological counterparts. Their interest in studying this reclusive, poorly known animal was being driven by a search for clues to the mode of life and natural history of t...
Graded Modality
This book explores graded expressions of modality, such as more likely than and quite possible, which provide a rich and underexplored source of insight into modal semantics. The volume explores and expands the typology of scales among English adjectives and uses the result to shed light on the meanings of a variety of epistemic and deontic modals.
Biomaterials Research Advances
Biomaterials serve as synthetic or natural materials used to replace parts of living systems or to function contact with living tissue. Biomaterials are intended to interface with biological systems to evaluate, treat, augment or replace any tissue, organ or function of the body. A biomaterial is different from a biological material such as bone that is produced by a biological system. Artificial hips, vascular-stents, artificial pacemakers, and catheters are all made from different biomaterials and comprise different medical devices. This book presents new approaches to biomaterial development including multi-field bone remodelling, novel strategies for conferring antibacterial properties to bone cement, polyacrylonitrile-based biomaterials for enzyme immobilisation and functionalised magnetic nanoparticles for tissue engineering from around the globe.

Premenstrual Syndrome
As the work on a revised edition of the Diagnostic and StatisticaL ManuaL (OSM-llIR) progressed, a great controversy grew over the inclusion of a new diagnostic category, "Premenstrual Phase Dysphoric Disorder." Some nosologists and scientists who study premenstrual syndrome (PMS) felt that, while a specific psychiatric disorder does exist, it occurs relatively rarely. The disorder can be characterized by recurrent periods of dysphoria on a monthly basis, in synchrony with the menstrual period. "PMS" already exists as a diagnosis in leD 9, the international medical nomenclature. The category for DSM-IIIR was to be a specific psychiatric disorder concentrating on the dysphoric reaction, and not including all of the physical and mental symptoms that people have ascribed to this condition. Much of the controversy that ensued had little to do with the diagnostic category or the condition itself. Rather, it concerned feelings voiced by feminist groups that the new diagnostic category would be misleading, that it would inappropriately label women as mentally ill, and that it would be affixed not only to the dysphoric disorder, but everything else that happens psychiatrically to women.
